A Califrnia family drives a car that culd help prtect the envirnment. When Jn and Sandy g t the stre r t their daughters’ sccer games, they drive in high-tech style. They drive a $1 millin, fuel-cell-pwered car. It may be the wrld’s mst expensive car and ne f the mst envirnmentally friendly cars. The FCX is the first fuel-cell-pwered car t be used by a family anywhere in the wrld. The FCX uses hydrgen and xygen fr fuel. Car makers have been wrking t develp vehicles that are better fr the envirnment. They are develping cars that use fuel ther than gasline.
And then what is fuel cell technlgy? Fuel cell technlgy wrks by changing the chemicals hydrgen and xygen int water. This prcess prduces electricity, and water vapr which cmes ut f the exhaust pipe. Mst cars release dangerus gases such as carbn mnxide and carbn dixide. Many scientists say these gases are majr cntributrs t glbal warming. “The FCX is driven just like any ther vehicle n the rad, but withut the gases which pllute the envirnment, ” scientists say. Fuel cell technlgy has been arund since the 1800s, but scientists have yet been t perfect it. They say it may take years befre the technlgy is ready fr widespread use. Anther earth-friendly car is already n the market. Hybrid cars use bth gasline and an electric mtr. They are becming mre ppular with custmers because they cut pllutin and imprve fuel efficiency.

Facebk users may feel scially successful in cyberspace but they are mre likely t perfrm prly in exams, accrding t a new research int the academic impact f the scial netwrking website.
Abut 83% f British 16 t 24-year-lds are thught t use scial netwrking sites such as Facebk, MySpace and Beb (视频博客), t keep in tuch with friends and rganize their scial lives.
“Our study shws peple wh spend mre time n Facebk spend less time studying, ”said Aryn Karpinski, a researcher in the educatin department at Ohi State University. “Every generatin has its distractins, but I think Facebk is a unique phenmenn. ”
Karpinski and a clleague questined 219 US undergraduates and graduates abut their study practices and general Internet use, as well as their specific use f Facebk.
They fund that 65% f Facebk users accessed their accunt daily (刷新个人主页), usually checking it several times t see if they had received new messages. The amunt f time spent n Facebk at each lg-in varied frm just a few minutes t mre than an hur.
The Ohi reprt shws that students wh used Facebk had a“significantly” lwer grade pint average—the marking system used in US universities—than thse wh did nt use the site.
“It is the equivalent f the difference between getting an A and a B, ”said Karpinski, wh will present her findings this week t the annual meeting f the American Educatinal Research Assciatin.
